Outcome of Four Point Fixated Open Loop Polymethyl Methacrylate Anterior Chamber Intraocular Lens: A Ten-Year Retrospective Study
PurposeTo study long term visual and refractive outcomes and complications in eyes with anterior chamber intraocular lens (ACIOL) implantationMethodsData of patients who underwent primary and secondary ACIOL implantation at L V Prasad Eye Institute, Bhubaneswar between 2011-2020 was collected, including details of post-operative visits. For analysis, sample was divided into: group Ia (primary ACIOL in cases without risk factors, n=104); group Ib (primary ACIOL in cases with pre-existing risk
... re-existing risk factors, n=49); and group II (secondary ACIOL, n=40).ResultsA total of 293 eyes of 288 patients were included. Mean pre-operative and last visit corrected distance visual acuity were 1.65±0.79 and 0.49±0.65 logMAR units in group Ia (p<0.001), and 1.46±0.74 and 0.52±0.72 logMAR units in group Ib (p<0.001). The mean spherical equivalent (MSE) for last refraction was -0.37 ± 1.05 dioptres (D) and -0.57 ± 1.04 D in groups I and II, respectively. Of 76 eyes in which addition of 2.5 D (over the near emmetropic posterior chamber intraocular lens power) was taken for ACIOL, 40 (52.6%) had MSE within ±0.5 D. Most common complications were transient corneal edema and anterior chamber reaction. Eyes on anti-glaucoma medications at last visit were eight (7.7%), 15 (30.6%), and two (5.0%) in groups Ia, Ib, and II respectively.ConclusionsWe observed that ACIOLs have good visual and refractive outcomes. Raised IOP is a concern in eyes with pseudoexfoliation, but can be managed with close monitoring. Hence ACIOL can be a good option for managing aphakia after cataract surgery.
